The role of height and weight growth in spontaneous resolution of vesicoureteral reflux.

BACKGROUND: The aim of this study was to investigate the role of height and weight growth in the resolution of primary vesicoureteral reflux (VUR). METHODS: We retrospectively evaluated the data of 74 males and 135 females who were diagnosed with primary VUR. According to the vesicoureteral reflux resolution, patients were divided into two groups. Patients with complete or partial resolution of VUR were included in Group 1 and patients with no resolution of VUR were included in Group 2. Patients were evaluated for weight Z-score, height Z-score and body mass index at the diagnosis and in the follow-up. In addition, age, sex, grade of reflux and laterality were recorded. RESULTS: There were no significant differences between the two groups, according to height Z-score, weight Z-score and body mass index at the diagnosis, in the follow-up and also annual changes of these parameters. In addition, the same parameters did not significantly differ in Groups 1 and 2, between the initial and final evaluations. However, when we evaluate the patients older than 12 months old, weight Z-scores were significantly higher at the final evaluation than at the diagnosis, in Group 1. This significant difference was not detected in Group 2 at the same age. CONCLUSIONS: Although we could not detect the hectic pace of height growth as being important in the prediction of long-term outcomes of VUR, weight growth should be considered to predict the resolution of VUR.

Systemic immune-inflammation index predicts in-hospital and long-term outcomes in patients with ST-segment elevation myocardial infarction.

OBJECTIVE: This study examines the predictive value of the novel systemic immune-inflammation index (SII) in patients with ST-segment elevation myocardial infarction (STEMI). METHODS: A total of 1660 patients with STEMI who underwent primary percutaneous coronary intervention (pPCI) were enrolled in the study. In-hospital and 3-year outcomes were compared between the four groups (Q1-4). The SII was calculated using the following formula: neutrophil*platelet/lymphocyte. RESULTS: The frequency of in-hospital cardiogenic shock, acute respiratory failure, acute kidney injury, ventricular arrhythmia, stent thrombosis, recurrent myocardial infarction, major adverse cardiac events and mortality were significantly higher in the high SII groups (Q3 and Q4). Logistic regression models demonstrated that Q3 and Q4 had an independent risk of mortality and Q4 had an independent risk of cardiogenic shock compared to Q1. Receiver operating characteristic analysis showed that the best cutoff value of SII to predict the in-hospital mortality was 1781 with 66% sensitivity and 74% specificity. Kaplan-Meier overall survivals for Q1, Q2, Q3 and Q4 were 97.6, 96.9, 91.6 and 81.0%, respectively. Cox proportional analysis for 3-year mortality demonstrated that Q3 and Q4 had an independent risk for mortality compared to Q1. CONCLUSION: SII, a novel inflammatory index, was found to be a better predictor for in-hospital and long-term outcomes than traditional risk factors in patients with STEMI undergoing pPCI.

The Predictive Role of a Novel Risk Index in Patients Undergoing Carotid Artery Stenting: Systemic Immune-Inflammation Index.

BACKGROUND: Inflammatory mechanisms play an important role in both atherosclerosis and stroke. There are several inflammatory peripheral blood count markers associated with carotid artery stenosis degree, symptomatic carotid artery lesions and carotid artery stent restenosis that reported in previous studies. However, the prognostic role of the blood cell counts and their ratios in predicting in-hospital and long-term outcomes in patients undergoing carotid artery stenting (CAS) has not been comprehensively investigated. Systemic immune-inflammation index (SII) proved its' efficiency in patients with solid tumors and its' role was rarely examined in cardiovascular disorders and stroke. The current study evaluated the effect of this novel risk index on in-hospital and long-term outcomes in a large patient population who underwent CAS. METHOD: A total of 732 patients with carotid artery stenosis who underwent CAS were enrolled to the study. SII was calculated using the following formula: neutrophil-to-lymphocyte ratio × total platelet count in the peripheral blood (per mm3) and the patients were stratified accordingly: T1, T2 and T3. In-hospital and 5-year outcomes were compared between the tertiles of SII. RESULTS: During the hospitalization, major stroke, ipsilateral stoke, myocardial infarction, death and major adverse cardiovascular events (MACE) rates were significantly higher in high SII level (T3) compared to SII levels (T1 and 2). In long-term outcomes, ipsilateral stroke, major stroke, transient ischemic attack, death, and MACE were significantly higher in the patients with higher SII level (T3). The 5-year Kaplan-Meier overall survival for T1, T2, and T3 were 97.5%, 96.7% and 86.0% respectively. In-hospital and 5-year regression analyses demonstrated that high SII was independently associated with MACE and mortality. CONCLUSION: SII was independently associated with in-hospital and long-term clinical outcomes in patients undergoing CAS. Immune and inflammation status, as assessed easily and quickly using SII, has a good discriminative value in these patients.

Association of C-Reactive Protein-to-Albumin Ratio With the Presence and Progression of Abdominal Aortic Aneurysm.

Aortic dilatation due to inflammation may lead to an increase in C-reactive protein (CRP) levels. We investigated the possible relationship between CRP-to-albumin ratio (CAR) and presence and progression of abdominal aortic aneurysms (AAAs). The study included 150 patients previously diagnosed with AAA (diameter 40-54 mm) and 100 normal controls. Clinical and laboratory parameters and maximal cross-sectional AAA diameters (measured by computed tomography angiography) were obtained from all participants at baseline assessment as well as after 1 year for those with an AAA. The patients with AAA had significantly higher serum CAR compared with controls at baseline (P < .001). Increased serum CAR was found to be an independent predictor of the presence of AAA (odds ratio: 3.162, 95% CI: 1.690-5.126, P = .001) after multivariate logistic regression analysis. There was a significant increase in aortic diameter and CAR after 1 year in the patients with AAA (P < .001; P = .003); a significant correlation was found between changes in the diameter of AAAs and CAR (r = 0.414; P = .005). Serum CAR may be useful as an inflammatory biomarker for the presence and progression of AAA.

Usefulness of CHA2DS2-VASc Score to predict clinical outcomes of patients undergoing carotid artery stenting.

The CHA2DS2-VASc score predicts stroke and mortality risk in several cardiovascular diseases regardless of atrial fibrillation. In this study, we aimed to investigate the ability of CHA2DS2-VASc score to predict in-hospital and long-term outcomes in patients undergoing carotid artery stenting (CAS). The study population included 558 patients undergoing CAS. The patients were stratified into three groups based on their CHA2DS2-VASc scores [low (≤ 2, n = 123), moderate (3-5, n = 355) and high (6-8, n = 80)]. In-hospital and 3-year outcomes were compared between the groups. In-hospital rates of ipsilateral and major strokes and death were significantly different between the groups (1.6% vs. 3.9% vs. 16.2%; 1.6% vs. 4.5% vs. 16.2%; 0.8% vs. 3.1% vs. 13.8%, p < 0.001 for all, respectively). At 3 years of follow-up, rates of ipsilateral and major strokes and death were significantly increased in patients with highscore compared to those with moderate and low scores (1.6% vs. 5.8% vs. 13%, p = 0.005; 0.8% vs. 5.2% vs. 13%, p = 0.001; 1.6% vs. 8.4% vs. 15.9%; p = 0.002, respectively). After adjusting for multi-model Cox regression analysis, CHA2DS2-VASc score persisted as an independent prognostic factor for mortality and major stroke in patients undergoing CAS. Higher CHA2DS2-VASc score predicted increased risk of in-hospital and 3- year stroke and mortality in patients undergoing CAS.

What should be the Optimal Carotid Stent Opening Rate Without Post-Dilation?

BACKGROUND: There is not a widely accepted optimal rate of stent opening in patients underwent carotid artery stenting. In this study we evaluated the effect of carotid stent opening rate (CSOR) without performing post-dilation on in-hospital and long-term outcomes. METHODS: A total of 825 patient patients underwent carotid artery stenting without post-dilation enrolled to the study. The patients divided into two groups according to their final CSOR (50% ≤ Post-stent deployment (SD) <80% and 80% ≤ Post-SD ≤ 100%). In-hospital and 3-year outcomes were compared between the groups. RESULTS: During hospitalization, the rate of ipsilateral stroke, major stroke and transient ischemic attacks were similar between the groups (respectively; 6.2% vs. 4.1, P = 0.190; 1.5% vs. 1.8, P = 0.811; 1.5% vs. 1.9%, P = 0.683). The 3-year Kaplan-Meier overall survival rates for the first and second groups were 87.6% and 84.4%, respectively (log rank test P = 0.426). The 3-year Kaplan-Meier overall cumulative ipsilateral stroke rates for the first and second groups were 88.0% and 88.6%, respectively (log rank test P = 0.409) CONCLUSION: Our study demonstrated that a CSOR higher than 50% without performing a post-dilation might be an effective therapeutic approach since there was not a significant difference regarding outcomes between the patients with a 50% ≤ Post-SD <80% and 80% ≤ Post-SD ≤ 100%. The need for post-stent balloon dilation might have been eliminated due to subsequent stent self-expansion.

Prognostic significance of pre-procedural prognostic nutritional index in patients with carotid artery stenting.

BACKGROUND: Inflammation and malnutrition play a critical role in the outcomes of patients undergoing carotid artery stenting (CAS). Prognostic nutritional index (PNI) is commonly utilized to evaluate the peri-operative immune-nutritional status of patients undergoing colorectal cancer surgery and is independently associated with survival. We assessed the association between immune-nutritional status, indexed by PNI, and outcomes in CAS patients. METHODS: A total of 615 patients hospitalized for CAS in a tertiary heart center were enrolled in the study. PNI was calculated using the following formula: 10× serum albumin value (g/dL) + 0.005 × total lymphocyte count in the peripheral blood (per mm3). In-hospital and 5-year outcomes (ipsilateral stroke, major stroke, transient ischemic attack, myocardial infarction, and mortality) were compared between the tertiles of PNI. RESULTS: In-hospital outcomes were similar between the groups except the increased mortality in decreasing tertiles of PNI. During a mean follow-up duration of 51.1 months, the lower PNI tertile was related to unfavorable outcomes. After adjusting for multi-model Cox regression analysis, PNI persisted as an independent prognostic factor for mortality and major stroke. CONCLUSION: PNI was independently associated with long-term mortality and major stroke in CAS patients. Malnutrition and inflammation, which can be assessed easily and quickly using PNI, have an important prognostic value in the patients undergoing CAS.

Rhabdomyolysis with different etiologies in childhood.

AIM: To investigate different etiologies and management of the rhabdomyolysis in children. METHODS: Eight pediatric rhabdomyolysis cases who applied to the Dokuz Eylul University Faculty of Medicine Department of Pediatric Nephrology with different etiologies between January 2004 and January 2012 were evaluated in terms of age, gender, admission symptoms, physical examination findings, factors provoking rhabdomyolysis, number of rhabdomyolysis attacks, laboratory results, family history and the final diagnosis received after the treatment. RESULTS: Average diagnosis ages of eight cases were 129 (24-192) ± 75.5 mo and five of them were girls. All of them had applied with the complaint of muscle pain, calf pain, and dark color urination. Infection (pneumonia) and excessive physical activity were the most important provocative factors and excessive licorice consumption was observed in one case. In 5 cases, acute kidney injury was determined and two cases needed hemodialysis. As a result of the further examinations; the cases had received diagnoses of rhabdomyolysis associated with mycoplasma pneumoniae, sepsis associated rhabdomyolysis, licorice-induced hypokalemic rhabdomyolysis, carnitine palmitoyltransferase II deficiency, very long-chain acyl-CoA dehydrogenase deficiency, congenital muscular dystrophy and idiopathic paroxysmal rhabdomyolysis (Meyer-Betz syndrome). CONCLUSION: It is important to distinguish the sporadic and recurrent rhabdomyolysis cases from each other. Recurrent rhabdomyolysis cases should follow up more regardful and attentive.

DNA methylation of the prestin gene and outer hair cell electromotileresponse of the cochlea in salicylate administration

Background/aim: Activity of the prestin gene may have a role in the pathogenesis of salicylate-induced ototoxicity. We investigated DNA methylation for prestin gene exon 1 in salicylate-injected guinea pigs.Materials and methods: Fifteen guinea pigs (30 ears) underwent audiological evaluation including 1000 Hz probe-tone tympanometry and a distortion product otoacoustic emission (DPOAE) test. The animals were randomly divided into three groups. Groups 2 (8 ears) and 3 (14 ears) were injected with intramuscular saline and sodium salicylate (200 mg/kg), respectively twice daily for 2 weeks. Group 1 (8 ears) received no injection. DPOAE measurements were performed at baseline; after 1, 2, 4, and 8 h (acute effect); and after 1 and 2 weeks (chronic effect). After audiological measurements, the animals were sacrificed for DNA isolation.Results: While a significant decrease (P < 0.01) was found for the acute effect in all frequencies in Group 3 according to baseline measurements, there was no difference in terms of chronic effect. DNA methylation increased during the acute phase of salicylate administration, whereas it returned to initial levels during the chronic phase.Conclusion: Salicylate-induced changes in DPOAE responses may be related to prestin-gene methylation. These results may have important implications for salicylate ototoxicity.

In-Hospital and long term results of primary angioplasty and medical therapy in nonagenarian patients with acute myocardial infarction.

Introduction: Although percutaneous coronary intervention is an accepted "first-line" therapy in acute ST elevation myocardial infarction (STEMI) in general population, few data are available on the short- and long-term outcomes of very old patients (age >90 years). Our aim is to evaluate and compare the short and long-term outcomes after primary percutaneous coronary intervention (PPCI) or medical therapy in nonagenarian patients with STEMI. Methods: We retrospectively identified patients older than 90 years old in our clinic, with acute STEMI who presented within 12 hours after symptoms onset, either underwent PPCI or medically treated. In hospital events and long-term results analyzed subsequently. Results: From January 2005 to December 2014, 73 patients with STEMI either underwent PPCI (PPCI group n = 42) or had only medical treatment (Non-PPCI group n = 31). Mean age was 92.4 ± 3.1 (90-106). Patients were followed 26.5 ± 20.1 months. Recurrent myocardial infarction during hospitalization was not observed in both groups. In-hospital mortality, cerebrovascular events and acute renal failure rate were similar between two groups (respectively P = 0.797 and P = 1.000, P = 0.288), whereas arrhythmia was significantly higher in the PPCI group ( 0; 21.4%, P = 0.009). Results show re-infarction was similar in both groups (respectively 3.2%; 11.9%, P = 0.382) but mortality in long-term was significantly lower in the PPCI group (respectively 40.9%; 12.9%, P = 0.02). Conclusion: In nonagenarian patients, with STEMI mortality is very high. Although; in-hospital events were similar, the long-term mortality rate was significantly lower in patients treated with PPCI.

The role of dynamic renal scintigraphy on clinical decision making in hydronephrotic children.

Hydronephrosis may be related to an obstructive cause, ureteropelvic/uretero-vesical junction obstruction or nonobstructive [vesicoureteral reflux (VUR)]. When an obstructive pathology is considered, dynamic renal scintigraphy may help to predict whether it is a true obstruction or not. In this study, we aimed to determine the contribution of dynamic renal scintigraphy with [99] mTc-MAG-3 to the clinical decision-making for surgery in hydronephrotic children. Files of the patients evaluated by MAG-3 scintigraphy for antenatal (AH)/postnatal (PH) hydronephrosis between 1992 and 2014 were reviewed. Gender, age, hydronephrosis (HN) grade by ultrasound (US), presence of VUR, MAG-3 result (obstructive vs. nonobstructive), ultimate diagnosis, and need for surgery were assessed. Cases with double collecting system and neurogenic bladder were excluded from the study. All of the patients had normal serum creatinine and eGFR. There were a total of 178 patients with 218 hydronephrotic renal units (mean age 34.7 ± 52.7 months; male/ female = 121/57, AH of 62%). MAG-3 was nonobstructive in 134 and obstructive in 84 hydronephrotic renal units. MAG-3 was obstructive in 47 of 121 (39%) males and 30 of 57 (53%) females (P = 0.058, odds ratio (OR) for obstruction was 1.9 for girls). MAG-3 was obstructive in 47 of 135 (35%) units with AH and 37 of 83 (45%) units with PH (P = 0.137). In 81 units with the society of fetal urology-4 HN by US, MAG-3 was obstructive in 55 (68%), and surgery was required in 52 of 55 (95%). Surgery was required for only two (7%) of the remaining 26 units with nonobstructive dilatation (P <0.001, sensitivity 96%, specificity 89%, OR 208). Antero-posterior diameter >16.5 mm was the best cutoff level for predicting obstruction by MAG-3 (sensitivity 75.2%; specificity 71%; OR 3.8). MAG-3 significantly affects clinical decision for surgery in HN. Hydronephrotic girls have more risk in terms of true obstruction. Combining MAG-3 with US improves the discrimination of true obstruction during follow-up.

Horseshoe kidney with growth retardation: Don't forget Turner syndrome.

Horseshoe kidney is the most frequent renal fusion anomaly that is usually asymptomatic and isolated malformation. However it can be seen with various syndromes and chromosomal anomalies. It was reported that 15-35% of Turner syndrome cases (TS) also display horseshoe kidney condition. TS is a chromosomal anomaly that had been characterized by delayed puberty, short body height and gonadal dysgenesis. In this report a five-year-old girl with horseshoe kidney, which has growth retardation during follow-up as only symptom of Turner syndrome.

Kinesio taping or just taping in shoulder subacromial impingement syndrome? A randomized, double-blind, placebo-controlled trial.

OBJECTIVE: To verify effects of kinesio taping (KT) in shoulder subacromial impingement syndrome (SIS) when compared to sham taping applied in the same way with KT. PATIENTS AND METHODS: Patients were randomized as group 1 (n = 21) KT group and group 2 (n = 20) sham-taping group. Taping was applied every three days, three times during the study period. We assessed all the patients at baseline, at the end of the taping period (12th day), and at one-month post-intervention. We assessed pain on the 100 mm visual analog scale (VAS). Shoulder range of motion (ROM), Constant Scores, and Nottingham Health Profile (NHP) scores were evaluated. RESULTS: Of the 41 participants, 13 were males (32%) and 28 were females (68%). The mean age was 45 ± 15 years (range 20-65 years). We documented a significant decrease in VAS for nocturnal pain, and Constant Score in both groups. The KT group showed additional significant change in NHP pain and physical activity scores. CONCLUSION: KT and sham taping generated similar results regarding pain and Constant Scores.

Antireflux surgery does not change ongoing renal functional deterioration.

AIM: Treatment modalities of vesicoureteral reflux (VUR) consist of antimicrobial prophylaxis and antireflux surgery. In this study, we aimed to determine if antireflux surgery changes the course of renal functional deterioration in children with VUR and urinary tract infections (UTI). METHODS: Medical files of patients with VUR diagnosed during evaluation for UTI were evaluated retrospectively for gender, age, follow-up period, and renal ultrasonography (US) and serial 99mTc-dimercaptosuccinic acid (99mTc-DMSA) scintigraphy findings. Estimated glomerular filtration rate and urinary protein levels were determined at the initial and last visits, and before the operation in children who had antireflux surgery. The patients were divided into two groups as solely medically treated (Group 1) and both medically and surgically treated (Group 2). Group 2 was further divided as those with stable renal function (Group 2a) and with progressive renal injury (Group 2b). RESULTS: There were 140 patients (77 female; mean age 51.6 ± 51.9 months). Group 1 and Group 2 included 82 and 58 patients, respectively. In Group 2, the number of patients with the abnormal US, DMSA scintigraphy, and renal function was higher than in Group 1. Recurrent UTI rate was similar, but progressive scarring was more prominent in the antireflux surgery group. In Group 2, 31 patients had a stable renal function (Group 2a) while 27 had progressive deterioration of renal functions (Group 2b). These subgroups were not different with respect to the rate of high-grade VUR, the presence of a renal scar in DMSA, and UTI recurrence. However, the bilateral renal scar was more common in Group 2b. CONCLUSION: Antireflux surgery does not change the course of ongoing renal injury and renal functional deterioration.

Does the presence of vesicoureteral reflux affect in vitro uropathogenic E. coli growth rate in urine?

BACKGROUND: Uroepithelial molecules like uroplakins are involved both in the development of urinary tract and in colonization, attachment and invasion of uropathogenic Escherichia coli (UPEC). Uroplakin disorders are also associated with vesicoureteral reflux (VUR). We hypothesized that urine contents, as well as urinary flow, may be altered in VUR, and aimed to determine whether in vitro UPEC growth is increased in urine from the refluxing systems. METHODS: Children evaluated by voiding cystourethrography for UTI were enrolled. Groups 1 and 2 included children with and without VUR, respectively. Sterile urine samples were obtained from all patients, and 2 × 10(2) cfu/mL UPEC suspension was inoculated into these samples. After incubation for 24 h, colony counts were assessed. Both groups were compared for UPEC growth and colony counts. RESULTS: Forty-two urine samples were included (21 in each group). UPEC was cultured in 9 (43 %) and 3 (14 %) samples in Groups 1 and 2, respectively (p = 0.040, OR 4.5). Colony counts were similar in both groups (log x; 2.36 ± 0.25 vs. 2.37 ± 0.12, p = 0.923). CONCLUSION: Inoculation of 2 × 10(2) cfu UPEC resulted in growth in almost half of the urine samples from refluxing systems, while UPEC growth was inhibited in most urine samples from non-refluxing systems suggesting that urine contents in refluxing units change in such a way that UPEC growth is facilitated.
